One of my computers has just crunched duplicate GPU work-Units.
Eeyore 4 and Eeyore 7 where both crunching p5761 (2-279-13).
Eeyore 4 log file, runs Machine ID 4.

Eeyore 4 is now running p5763 (2-335-4) and Eeyore 7 now has p5763 (3-336-4).
I hope I get credit for both work-units crunched.
Luck ............

There is no report in the Mod database indicating those WUs have been credited yet.
If the duplicate WUs were a result of you manipulating the files (e.g.- moving work from one computer to another) you probably will only get credit for one of them. If the duplication was a result of normal server assignments, you'll probably get credit for both of them.

The box has been up for well over a month unattended.
Its running 8 nVidia GPU clients.
Its only the second time I've seen it grab duplicate work-units.
The time before, two of the client down-loaded the same work-unit at the same time.
Thanks for the heads-up.

I just checked and Tigerbiten, Team 33, did get credit twice.

Just picked up on another pair.
I'm crunching p5016(9-702-5) twice.
It seems to happen when the box downloads two work-units at the same time.
This time both connected to the work server at 10:00:17.
I'm just reporting it in case its a glitch.
Or does Stanford send out a few of copies of each work-unit and am I being lucky/unlucky enough to grab two of them.

The servers are not supposed to issuing the same WU untill the after first deadline has elaspsed.

They are not supposed to do so, but it sometimes happen in a situation described by Tigerbiten (two clients ask for a WU simultaneously).

I've probably done well over 13k work-units on this box spread over 8 GPU cores and this is only the 3rd time I've seen it happen.
In each case the two clients have asked for a work-unit at the same time and got the same one.
